My mother ran a special school on a mission station in southern Africa in the early 1960's that was unlike any other school on any other mission station in the world. The station we lived on was one hundred miles from the nearest city out in the African bush which meant mom could do pretty much as she pleased. We were the only missionaries stationed there and the only white people in miles.
At that time the country was ruled by the white minority just like in South Africa. Since mom controlled my father, it meant she controlled the entire mission including me and my older sister. She had put my older sister in charge of me which my sister took to mean that she was supposed to make my life as miserable as possible. She would demand that I do things that were extremely embarrassing like walk around the house with my penis poking out of my shorts and kept hard by a constricting band that she had placed on the base of it.
Khaki shorts were what was worn most of the time other than on Sunday at which time we wore white shorts. She would make sure mom and the African girl who worked in our house saw and played with my penis while it stuck out of my Khaki shorts. I had just turned eighteen and my cock was always hard anyway, but my sister made sure I was tortured. Not only could the blood not get back out of it so the erection could go down, but the sperm could not get out either so I could not have an orgasm.
My sister was two years older than me. She was a fat twenty year old girl who liked the feeling of having power over a man. The nipples on her over sized boobs would harden the minute she started her routine with me. I could see them through the thin tee shirts she wore because she never wore a bra to hold her fat breasts. Her shorts barely cover her big butt and they came up into her pussy lips always making a nice camel toe. She always made me hard before she ever called the housegirl in to her room to undress me so she could put the cock ring on the base of my cock for the day.
The rule was the housegirl, Emma who had left her home after turning 18 and with her father's blessing, had to take girl dress off at the door to my sister's bedroom. Emma always wore the same dress which she washed in the same tub of water she bathed in outside of her small hut behind our house. She washed her dress almost every night, but she bathed every night. Many nights I stood as she washed her firm young titties and between her legs. I would always play with my cock as I watched her. Her titties were not fat like my sister's and my mom's. Emma would have worn a dd cup bra if she had had a bra, but her titties did not droop. She had a firm muscled butt that stuck out and her pussy lips were fat and protruding. Her clit was like a small penis. When she washed her pussy as I watched she would squat and pull her lips open and play with her clit all the time looking straight at my cock which I had out. Her bathing show always made me come.
Emma like to be called to my sister's room to undress me and get my penis hard for my sister to put the cock ring on. After removing her dress she would squat and show us her nice pussy and then crawl over to me and start by taking my shorts down. Emma loved my cock and to see it grow. She liked it when it got to its almost full ten inches and the big head would fill with blood and pre-cum. She would lick my peehole like she was trying to get her tongue in it. My sister loved to see her worship my cock. She played with her boobs and rubbed her fat pussy through her shorts.
"Bend over Jeff and let Emma at your asshole," my sister Kris said without missing a stroke on her engorged pussy. "Don't forget and cum while she is doing it you horny bastard," she added with some difficulty talking because she was breathing fast.
Emma started licking my nuts and then she pulled my ass cheeks apart and stuck her tongue straight onto my anus. I jump a little, but she had hold of my cock by then and pulled me back and tongued my anus as she pumped my cock with both hands. My sister came around bent low enough to kiss me on the lips and then she gave me a tit to suck on. She had pulled her tee shirt up and they were both hanging there, but she only offered me one. She played with the other.
"Forget our toy Emma and get over here and eat my pussy," she said in a voice the housegirl knew not to ignore.
I had been so caught up in the sensations I was feeling I did not know when my sister had left with her tit and gone to her bed and gotten on her back naked and spread her legs wide.
"Get up here and eat girl and make sure Jeff can fuck your pussy," she said. "Put all ten inches in her brother, but don't cum because we don't want no mix baby on this mission station."
